Mindblowing future technology predictions of the future?

Hello all. Nice to meet you. I don't want to know whats smaller than a quark but I am sure many here have spent a lot of time thinking about the future. In terms of new technology. I have some of my own theories for some of things that we'll definitely see in the future. I'm betting on flying cars under 100 years 5th element style although it will probably be more Blade Runner haha

But I would love to hear any of your thoughts and predictions no matter how wacky they might sound. It could be anything at all. Do you know of some new mindblowing technology or have a prediction about flying cars too? haha they all laughed at the Wright brothers and now look.

Ok so laugh now but I will return to this thread in another 50 years to check replies and see if I was right. ;)
